How It Works

MNEVI provides proof that a digital file existed at a specific moment in time.

1. Upload Your File

You upload a digital file. The system does not read or interpret its content.

2. Hash Generation

MNEVI calculates a SHA-256 cryptographic hash. This hash acts as a unique digital fingerprint of the file.

3. Timestamp Creation

A UTC timestamp is generated at the moment of submission. The hash and timestamp together form proof of existence.

4. Certificate Issued

A PDF certificate is generated containing:

• File name
• SHA-256 hash
• UTC timestamp
• Receipt ID

5. Independent Verification

Anyone can verify the file by recalculating its SHA-256 hash. If the hash matches the certificate, the file is identical to the original submission.
